lifelong care for your rainwater system
Rainwater Exchange cares for hundreds of homeowners across Texas, whose systems were installed by many different companies. We specialize in maintenance, parts, and monitoring, and have a network of qualified installers for new builds. All built on 15 years in the field.
WHY RAINWATER
Aquifers are drying. A new well runs $30K–$60K — with no guarantee you’ll hit water.
Meanwhile, every time it rains, your roof sheds thousands of gallons of clean water. A whole-home system captures it, filters it to drinking quality, and delivers it to every tap in your house.

The Rainwater Exchange grew out of Cqure Water, a pioneer in rainwater harvesting for whole-home and potable use in Texas. We're now building the platform on that experience to deliver the education, protocols, products, and the certified installer network to make rainwater harvesting the first, mainstream choice for water independence.
